CORN AND COB CRUSHER AND GRINDER.

SPECIFICATION forming part of Letters Patent No. 792,186, dated June 13,1905. Application filed October 21,1902. Serial No. 128,176.

To all whom it may concern.'

Be it known that I, ABRAHAM M. ZIMMER- MAN, a resident of New Holland,in the county of Lancaster and State of Pennsylvania, have inventedcertain new and useful Improvements in Corn and Cob Crushers andGrinders; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to an improvement in corn and cob Crushers andgrinders, and more particularly to improved means for regulating thefeed of such machines, the object of the invention being to provideimprovements of this character in which the size and shape of thefeed-opening can be regulated at will to give the best results andprovide feed-regulating means which will be extremely simple inconstruction, easy to operate, and cheap to manufacture.

With these objects in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in section illustratingmy improvements. Fig. 2 is apartial sectional view taken at right anglesto Fig. 1 and omitting parts 3, 5, and 6; and Figs. 3 and 4 are views ofthe grinding-plates removed from the machine, the dress on the platesnot being shown. Fig. 5 is a longitudinal sectional view of the machine.

1 represents a supporting-frame, on which a hopper 2 is mounted anddirects the corn and cobs into a horizontal cylindricalcrushing-receptacle 3, through which a shaft 4 projects longitudinallyand carries crushing-fingers 5, which cooperate with a concave 5a tocrush the cobs and corn. Communicating with one end of thecrushing-cylinder is a grinding-chamber 6, into which the crushed cobsand corn are fed, as will more fully hereinafter appear. In thegrinding-chamber at one side a guide-plate 7 is located and is providedwith a large opening 8 for the passage of the crushed material. Theopening 8, however, is partially closed by a stationary verticalgrinding-disk 9, having an opening for shaft 4 and a segmental openingor feed-passage 10 around the lower half of the shaft. A grinding-diskl0 is secured on the shaft to cooperate with the stationary disk andgrind the material between them, and asuitable outlet-spout 6 isprovided on chamber 6, through which the ground material escapes.

Plate 7 is provided with a recessed extension 11, having elongated slots12 therein for the reception of bolts 13 and thumb-nuts 14 to secureslides 15 and 16, respectively, at any position desired. The upperslide, 15, is adapted when moved to its closing position to abut againstthe shaft 4 and close the upper portion of the feed-passage lO, whilethe lower slide, 16, closes the lower larger portion of said opening orfeed-passage.

It will thus be seen that by employing two slides one or both of themcan be adjusted not only to regulate the size of the feed-passage, butalso the shape thereof. For instance, lower slide 16 when alone movedwill give a feed-passage entirely below the shaft, and thus permit acomparatively rapid feed, while if the upper slide 15 is alone moved thefeed will be slower, and if both are moved the most rapid feed will begiven the machine.

The adjustment of the slides can be readily accomplished by looseningthumb-nuts 14, moving the slides, and clamping them in position by thenuts.

A great many changes might be made in the general form and arrangementof the parts described without departing from my invention, and hence Ido not confine myself to the precise construction set forth, butconsider myself at liberty to make such slight changes and alterationsas fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-n 1. A feed mechanism for mills, comprisinga plate having a feed-opening therein and provided with an extension, astationary grind-` ing-disk having a segmental feed-opening thereinbelow the axis thereof, said disk secured to said plate, a slide locatedbetween IOO disk and plates and adapted to be made to eX- tend acrosssaid segmental feed-opening, and means for independently securing slidesto the extension on the fixed plate in any desired adjustment forregulating the size and shape of the segmental feed-opening.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
